This paper addresses the problem of fault estimation observer design with finite-frequency specifications for discrete-time Takagi–Sugeno (T-S) fuzzy systems. First, for such T-S fuzzy models, an $H_\infty $ fault estimation observer with pole-placement constraint is proposed to achieve fault estimation. Based on the generalized Kalman–Yakubovich–Popov lemma, the given finite-frequency observer...
This paper proposed a green transmission power control scheme for cellular networks in the smart grid environment where several electricity retailers offer different prices to the BSs. The power allocation of each BS is formulated as a non-cooperative game. In a dynamic environment, the competition behaviors of BSs are modeled as a stochastic learning process and a conjecture based multi-agent reinforcement...
Atmospheric turbulence is one of important factors to affect UAV flight smoothly. To reduce the influence of atmospheric turbulence, active disturbance rejection controller is designed in this paper. Firstly, mathematical models are built for UAV movements and atmospheric turbulence. Secondly, the altitude controller and the lateral deviation controller with linear state equations are designed. Finally,...
The behavioral experiment presented in this paper investigated deception tasks (both concealment and lying) undertaken in a public space. The degree of risk of deception detection and the demands of self-regulation when deceiving were manipulated. The results showed a significant interaction effect between veracity and risk of deception detection, emerged for the body movement of “hand(s) in pocket(s)”...
Hard disk protection cards with a network clone function are widely used in universities at present to protect hard disk data. In this article, the working principle and optimized settings of the protection card has been demonstrated, and problems which may be easily emerged during its operation have also been analyzed. Besides, the corresponding solutions have been put forward.
This paper addresses the fault estimation problem for discrete-time dynamic systems. First, using a specific system decomposition, we propose a new reduced-order fault estimation observer (RFEO) with multiconstrained idea. A detailed discussion of the RFEO is given. Then, with the help of the slack-variable technique, fault estimation performances are further enhanced to reduce the conservatism generated...
To the traditional diagnosis of motor dysfunction and present situation of the method of restored to health treatment, this paper researches detection method of movement function and movement posture, which established movement function barrier patients upper limbs motion model and posture position calculation model, realized quantitative description of the parameters for motor dysfunction limb motion...
